"Literally opposite Aso train station if arriving by train. Has plenty of parking and less than thirty minutes drive to the volcano visitors center. Feels brand new in 2025.
Realistically you are going to need a car to have options for dinner etc. "
"The place offers deep tubs in each room as well as a public ofuro. I didn't get to use the (milky way) onservatory due to weather conditions, but it is available. The best part for my stay was however was due to the friendly owner. He had given me info for best local spots and I enjoyed my chat with him. Hope his business prospers."

There are free private onsen 45 mintues 1 time. But the public onsen is so good either. "
